Jim.

Console mode not working on some computers,
but xboard mode '-xboard' is working ok.
Should work on Win98 too in xboard mode.

Jim.

Well done Jim !!

I'm having trouble getting Slibo to run under Arena 1.1 on my XP box. This is what the debug output is giving me:

Hi Tony,

Looks like it's crashing fo you on the 'protover' command. Try running engine in old Winboard 1 protocol (which will disable this command)
till I can fix it.

Jim.

I have found a small error in the protover command. Maybe this was causing the crash.

Hi Jim. I'm sorry for being a pain in the butt. I was getting the same message, whether or not I used the Winboard or Winboard (old) setting, even with the bugfix b version.

It did work fine, however, on my AMD Turion laptop running Windows XP x64 edition. The machine that was having problems is a plain jane Pentium 4 running XP Professional.

I also did notice one other thing, Slibo doesn't like controls of game in x minutes, with or without an increment. I was trying faster time controls like 3/0 and 1/1. It takes too much time using those particular time controls. It's ok with x moves in y minutes type time controls. I guess this was something that was a problem before the Windows port.

This is very true, dear Doctor...

Andrew also made for me a version of KnightCap that does not need the cumbersome installation tricks of the public version. Mine can even use an external book

Olivier

Now why are you keeping it all to yourself (Knightcap-that is)?

Hi Dario

Nice to see you here

It is just because I am evil, of course

I'll ask Andrew if it is OK to pass his compile to other people or to make it available for download.

Olivier

Thank you, that would be really great.

Yes I'm back, trying to catch up...all the new engines and upgrades, quite daunting.
It will keep me out of mischief ....for a while.

Keep up the good work on the site, it's very much appreciated.

Best
Dario

Cool,I love this program for it's evaluation learning feature although it's hard to install it and make it running softly....
I don't have enough games yet to confirm if this feature is of any help to improve the program performance....
Cheers,
Dr.D

Update:

Changes: (0.4.5)

1. Removed ncurses library dependency.
2. Fixed setboard/analyze support under winboard.
3. Fixed checkmate crash.
4. Fixed time control problems.
5. Fixed bookthinker support.

Hi Jim,

I have a litlle problem with the engine Slibo v0.4.8. It does not work on my PC under Arena 2.01. I installed it as a WB engine, but it creates a file with extension stackdump. This is what it has inside:

What could be the problem?

Hi Carlos,

I have had a report about Slibo not working on Pentium D before. I think this is a Cygwin issue.
Using an older version of Cygwin for compiling may solve it. I'll compile it and put up link here
later.

Jim.

Thank you Jim. I am looking forward to it.

On the other hand, I was testing your Braincrack and CPW compiles under Arena 2.01 and noticed that both ponder (even when I set ponder to OFF in a tournament), but they simply use the other core while the other engine is thinking. Is there anyway to fix this, adding some commands perhaps?

Best,
Carlos

Maybe CPW src has been updated a little since I compiled it. I will check.
This this is known bug in Braincrack. I have looked at this before a while back.
I'll take another look.

Jim.

I compiled a new Slibo for you to test.

Thanks Jim, it works fine now.

I made it play with Dabbaba 1'+1" to test it under Arena 2.0.1, and it was winning, but lost at the end on time.
